York at night taken on 22 Dec, 2018 during the "Blue Hour" which happens twice a day, just before sunrise and just after sunset. It lasts between 20 to 40 minutes, depending on the weather, and your geographical location. During this time, the sky can turn different shades of blue and reflect orange, yellow, purple and pink. This was the first attempt at doing this and in January, 2019 I will be having classes from the Photography Landscape Artist Chris Ceaser to better learn this technique of Landscape Photography.
